Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, pursuant to the answer of 28 November 2017 to Question 115232, how many claimants of Employment and Support Allowance were subject to payment miscalculations in each (a) 2011, (b) 2012, (c) 2013, (d) 2014 and (e) 2015, and what the timetable is for those claimant to be reimbursed.

The Department estimates that around 270,000 cases need to be looked at again and that around 75,000 of those cases (5% of the population transferred over from incapacity benefits) may have been underpaid. The Department has already started contacting individuals to establish if there has been an underpayment of premiums and a small number of claims have already been corrected and the arrears that are due have been paid. The Department expects to complete the review and correct cases by April 2019. We will update the House shortly.
